On the morning of my Tokyo Skytree visit, I'd like to have a quick Japanese-style breakfast. Do you have any recommendations nearby?

I recommend MISOJYU, a miso soup specialty restaurant located on the 1st floor of Tokyo Solamachi!
It's directly connected to Oshiage Station, so access is super easy, and it opens from 9:00 AM.
You can choose from five types of miso soup and five types of rice balls, and if you get a set, it even comes with a soft-boiled egg and small side dishes—which is such a nice touch.
The miso is an original blend, and the ingredients are generously cut, so it's surprisingly hearty for a simple breakfast.
The shop has both sofa and counter seating, making it comfortable even for solo visitors.
They also accept major credit cards and transportation IC payments, so it's very convenient for travelers. ☕🍙
